Moms- day to self?

Do you guys get days to yourself ever? I’ve been thinking about asking my mom if she would be okay with watching my 18 month old daughter one day each week so I can have a little time to myself. My mom isn’t working and I don’t have a baby sitter. Thoughts? Really never get out and do anything for myself or have any time and I feel like that is important. Anyone do this or something similar?
